Abstract
The utility model discloses a kind of deformable rolling wheel centralizer, comprise centralizer body, centralizer body is evenly distributed with righting strip, groove is provided with in the middle of righting strip, be provided with roller in groove, also comprise fixed axis, fixed axis is connected with roller and is fixed on righting strip.A kind of deformable rolling wheel centralizer, there is when entering well and being obstructed certain elasticity can yield deformation shrink, undergauge well section can be passed through smoothly, setting of casing resistance can be reduced by roller when high-angle wells and horizontal wells, simultaneously can also righting sleeve pipe ensure its centralizer in the wellbore, arrange groove, roller, the fixed axle structure when can guarantee yield deformation occurs of reinforcing rib are stablized.
Description
Technical field
The utility model belongs to petroleum drilling engineering technical field, relates to a kind of deformable rolling wheel centralizer.
Background technology
In petroleum drilling engineering well shaft fixing technology process, reduce setting of casing resistance in order to ensure sleeve pipe centralizer in the wellbore, usually can adopt at jacket application dress rigid centralizer or elastic centralizer, but due to rigid centralizer poor flexibility, not yielding, jam phenomenon may be there is by during undergauge well section in casing job process, cause and sleeve pipe mentions transfer difficulty, there is certain safety hazards; And because elastic centralizer is in extended reach directional well and the well cementing operation of horizontal well horizontal segment, be unfavorable for the reduction of sleeve pipe frictional resistance.Therefore existing centralizer is difficult to meet the setting of casing cementing requirements in Holes of Complicated Wells body structure situation.
Utility model content
The purpose of this utility model is to provide a kind of deformable rolling wheel centralizer, not only can reduce setting of casing resistance and can also guarantee the centralizer of sleeve pipe in well.
The technical scheme that the utility model adopts is: a kind of deformable rolling wheel centralizer, comprise centralizer body, centralizer body is evenly distributed with righting strip, groove is provided with in the middle of righting strip, in groove, roller is installed, also comprise fixed axis, fixed axis is connected with roller and is fixed on righting strip.
Feature of the present utility model is also:
Righting strip is centre outwardly shape.
Reinforcing rib is provided with inside righting strip.
Roller protrudes from the external surface of righting strip.
Gap is there is between righting strip and centralizer body.
The beneficial effects of the utility model are: a kind of deformable rolling wheel centralizer of the utility model, there is when entering well and being obstructed certain elasticity can yield deformation shrink, undergauge well section can be passed through smoothly, setting of casing resistance can be reduced by roller when high-angle wells and horizontal wells, simultaneously can also righting sleeve pipe ensure its centralizer in the wellbore, arrange groove, roller, the fixed axle structure when can guarantee yield deformation occurs of reinforcing rib are stablized.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of a kind of deformable rolling wheel centralizer of the utility model.
In figure, 1. centralizer body, 2. righting strip, 3. gap, 4. groove, 5. roller, 6. reinforcing rib, 7. fixed axis.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of deformable rolling wheel centralizer of the utility model, as shown in Figure 1, comprise centralizer body 1, centralizer body 1 is evenly distributed with righting strip 2, in the middle of righting strip 2, be provided with groove 4, roller 5 is installed in groove 4, also comprise fixed axis 7, fixed axis 7 is connected with roller 5 and is fixed on righting strip 2, and righting strip 2 is in centre outwardly shape, be provided with reinforcing rib 6 inside righting strip 2, roller 5 protrudes from the external surface of righting strip 2.
During use, centralizer body 1 is enclosed within jacket exterior, then casing job is carried out, when running into undergauge well section, what the borehole wall and sleeve pipe applied makes a concerted effort the radial yield deformation of righting strip 2 is shunk, thus smoothly by undergauge well section, setting of casing resistance can be reduced by roller 5 when high-angle wells and horizontal wells, simultaneously can also righting sleeve pipe ensure its centralizer in the wellbore.
A kind of deformable rolling wheel centralizer of the utility model, there is when entering well and being obstructed certain elasticity can yield deformation shrink, undergauge well section can be passed through smoothly, setting of casing resistance can be reduced by roller when high-angle wells and horizontal wells, simultaneously can also righting sleeve pipe ensure its centralizer in the wellbore, arrange groove, roller, the fixed axle structure when can guarantee yield deformation occurs of reinforcing rib are stablized.
